Help me with the steps for y = 4x + 2 please.

You are correct. 4 is the slope and 2 is the y intercept.

Reasoning:

y = mx + b is the slope intercept form of a line
m stands for slope
b stands for y intercept

In your case, m = 4 and b = 2.

The product of two numbers is 144, but their sum is -24. What are these two numbers?

stepladder [879]

Answer:

The two numbers are - 12 and - 12 .

Step-by-step explanation:

Let the two numbers be x and y then

By the question

x * y = 144

or x = 144 / y ....... I)

Again

x + y = - 24

Or 144/y + y = - 24

or, ( 144 + y²) / y = - 24

or, 144 + y² = - 24y

y² + 24y + 144 = 0

y² + ( 12 + 12 ) y + 144 =0

y² + 12y + 12y + 144 = 0

y(y + 12 ) + 12 ( y + 14) = 0

( y + 12 ) ( y + 12 ) = 0

Either

y + 12 =0

y = - 12

Now

x = 144 / - 12 = - 12

Therefore the two numbers are - 12 and - 12 .

Hope it will help :)❤

A basketball player is shooting a basketball toward the net. The height, in feet, of the ball t seconds after the shot is modele

arsen [322]

The shot was blocked between 0.84 and 0.85 seconds after the shot is launched.

<h3>what will be the time in which the blocker will block the ball?</h3>

The given equation for ball height

$=6+30t-16t^{2}$

The equation for the blocker's height will be

$=9+25t-16t^{2}$

But, the shot is made before two-tenths of a second or 0.2 seconds therefore modified equation for ball height is

$=6+30(t-0.2)-16(t-0.2)^{2}$

Now for the shot to be blocked, the height of the shot-blocker must be greater than the height of the ball which is shot before 0.2 seconds :

$9+25t-16t^{2} \geq 6+30(t-0.2)-16(t-0.2)^{2}$
